A musique concrete compositions written in 1967 by Luc Ferrari used for a television program by C. Caspari, using recordings Ferrari made in 1966 at an exhibition of Jean Tinguely's frantically moving sculptures; plus a 1964 soundtrack to a 33 minute black-and-white film by Jean Barral.

A fascinating rendering of Ferrari's Tautology--everyday activities enacted in gesture, noises, words, &c.--used as a framework for a chamber work where the performers recorded their parts independently, which were then overlapped and played alongside Ferrari's tapes and narration.
